Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am trying to set up a scheduled job on one of my workstations (RH7.3 - fully up2date). The job is to FTP a set of TAR files from several servers as a backup.

I can execute the appropriate FTP commands from the command line and everything works fine.

However, when I execute a shell script to do the same commands (login to the servers via FTP, move to the appropriate directory, and then mget the files), the downloaded files are 24 bytes shorter than the files on the server and unusable.

Has anyone encountered this situation? Any ideas as to what's going on and how to fix it?
